No ALPN, only NPN with http2

[Synchro]

Ah, this is probably the problem:

    built with OpenSSL 1.0.1f 6 Jan 2014

I'll open a ticket on the package repo to see if it can be built with a
later version. Oddly, I can't find any mention of ALPN support in the
openssl release notes at all: https://www.openssl.org/news/changelog.html

This is the complete output:
